• How do I obtain an HtmlHelper<TModel> instance for a model in ASP.NET MVC?

  - by DanM

  Let's say I have an Index view. The model I pass in is actually a collection of models, so the Html property is of type HtmlHelper<List<MyModel>>. If I want to call extension methods (e.g., Display() or DisplayFor() on the individual items in the list, however, I think I need to obtain an HtmlHelper<MyModel>. But how? I tried using the HtmlHelper<TModel> constructor, which looks like this: HtmlHelper<TModel>(ViewContext, IViewDataContainer) But I'm not having any luck with that. I don't know how to obtain the IViewDataContainer for the item, and the documentation on these things is very sparse. A lot of magic apparently happens when I do... return View(List<MyModel>); ...in my controller. How do I recreate that magic on individual items in a list/collection?

• ASPNET MVC what do you call this, a partial view? Or something else?

  - by JK

  I'm trying to google for info on a situation, but I dont know what it is called, so its hard to find results :) I have a model with say 10 fields. But only some of those are shown on a particular view, lets say 3 of them: id, name, date. What do you call this kind of view that does not display the whole model? A partial view? The problem is that because 7 fields are not sent to the view, when the Update action is called on the controller, those fields are null, and the DB gets updated with those 7 fields set to null.

• ASP.NET : What exactly is affected when Javascript is off?

  - by rlb.usa

  I've heard different stories about ASP.NET and JavaScript: that it works fine with Javascript turned off, that only some parts don't work, and that nothing works at all. How exactly are ASP.NET applications affected if JavaScript is turned off in a client's browser? What parts don't work (if any)? For example, will RequiredFieldValidators still work? What about UploadControls? AJAX UpdatePanels and AsyncPostBack's? FileUploads? Do page codebehinds still run? Forgive my ignorance, I can't seem to find much about the issue that is in-depth.

• In Spring MVC, is it possible to have different return types in one request handler method?

  - by Bobo

  For example, if a request succeeds, I will return a View ,if not, return a String indicating error message and set the content-type to either xml or json. Based on what I read, seems like I should use "void" as the return type for handler methods. Check this out: "void if the method handles the response itself (by writing the response content directly, declaring an argument of type ServletResponse / HttpServletResponse for that purpose) or if the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)."(Spring Framework reference). What I dont understand is what " the view name is supposed to be implicitly determined through a RequestToViewNameTranslator (not declaring a response argument in the handler method signature)" means? Any anyone give me an example?

• Why does the default view for a List in ASP.NET MVC use 'var' to iterate through the items?

  - by SLC

  The title pretty much sums it up, it puts the following line of code in: <% foreach (var item in Model) { %> As the View is auto-generated and uses reflection to work out exactly what item is, so you get intellisense and everything, I just wonder, why do they use var rather than the actual type?

• How to Pass complex objects in ASP.NET MVC using Get parameters?

  - by VJ

  I am wanting to pass something like the following to my view from my controller via GET not POST: public class MyDTO { public string val1 { get; set; } public string val2 { get; set; } public MyObject obj { get; set; } } public class MyObject { public int SomeInt { get; set; } public string ACoolValue { get; set; } public string YetAnotherCoolValue { get; set; } } And then the controller would like like this. (Note it is a GET): public ActionResult MyView(MyDTO dto) { return View(dto) } The problem is that the instance of MyObject is coming back as null, where val1 and val2 have data. Has anyone run across this?

• .NET-MVC Modelbinder not binding because of primary key, all other fields are right. What's happenin

  - by ropstah

  I want to perform an Add object scenario in .NET using the modelbinder. Function AddObject() As ActionResult Return View() End Function <AcceptVerbs(HttpVerbs.Post)> _ Function AddObject(<Bind(Exclude:="ObjectId")> ByVal o As BLL.Object) As ActionResult o.Save() End Function However, I get an error: 'o.ObjectId' is not declared or the module containing it is not loaded in the debugging session. While inspecting the object, all other fields are set properly. I've tried all combinations regarding: with/without Html.Hidden("ObjectId") to with/without <Bind(Exclude:="ObjectId")> and even setting o.ObjectId to Nothing, all with the same results. What am I doing wrong?

• why would i get a different views when called from different controller actions in asp.net-mvc

  - by ooo

  I have 2 different controller actions. As seen below, one calls the same view as the other one. The fitness version has a bunch of jquery ui tabs. public ActionResult FitnessByTab(string tab, DateTime entryDate) { return View("Fitness", GetFitnessVM(DateTime.Today.Date)); } public ActionResult Fitness() { return View(GetFitnessVM(DateTime.Today.Date)); } private FitnessVM GetFitnessVM(DateTime dt) { FitnessVM vm = new FitnessVM(); vm.Date = dt; // a bunch of other date that comes from a database return vm; } the issue is that on the action FitnessByTab() the tabs dont load correctly but on the Fitness() it loads fine. How could this be as my understanding is that they would be going through the same code path at that point. As you can see i am hard coded both to the same date to make sure its not a different date causing the issue. EDIT Issues has been solved. It was the relative referencing of all my links. I didn't get any issues until i used firebug that highlighted some missing references due to "../../" instead of Url.Content("
